    1. On the prop shaft seal, assume you mean part #35 in the ME diagram. The Sierra replacement seal should just be pressed into the oil seal housing – no perimeter gasket is needed. Yes, the lip side of the oil seal with the retention spring should face the oil side of the shaft.

    2. The shift rod bushing can be knocked out with a 5/16″ punch but it takes a long punch to reach it. If you think you’ll be collecting more motors, it helps to have the original OMC service tool, part #304514 to remove and install the bushing.

    3. Not sure on this one.
